非常新的文献，对尾流的研究目前还有很多工作，有意愿者继续努力吧！特将此文献给学友(ship torpedo)

燃料电池电源matlab仿真 分为PEMFC和SOFC的分布式发电(Matlab simulation of distributed power supply for fuel cell Distributed generation divided into PEMFC and SOFC)

说明：  An Android File Manager source code that supports decompression can also be used for routine operations such as copying, moving, deleting and renaming. When compressing files, they can only be compressed into ZIP format, not rar format. Decompression also supports ZIP format tightly. Source code has more detailed annotations.

分析了永磁同步电机矢量控制的发展概况，然后从机电能量转换的角度出发，解释三相永磁同步电机的机电能量转换原理，推导拉格朗日运动方程。此外，列写出永磁同步电机在三相静止坐标系和dq坐标系下的数学模型。基于Simulink建立了转速电流双闭环矢量控制系统的仿真模型，通过对仿真结果分析，验证了永磁同步电机矢量控制系统性能的优越性(The development of vector control of permanent magnet synchronous motor is analyzed. Then, from the perspective of electromechanical energy conversion, the principle of electromechanical energy conversion of three-phase permanent magnet synchronous motor is explained, and the Lagrangian motion equation is derived. In addition, the mathematical model of the permanent magnet synchronous motor in the three-phase stationary coordinate system and the dq coordinate system is written. Based on Simulink, the simulation model of the speed and current double closed-loop vector control system is established. The simulation results are analyzed to verify the superiority of the performance of the permanent magnet synchronous motor vector control system.)
